(B) Sexual reproduction involves the formation and fusion of gametes. In humans,gametes (sperm and ovum) are produced through the process of meiosis. Meiosis is a reductional division that reduces the chromosome number to half. Therefore,human gametes are haploid $(n)$,containing $23$ chromosomes each. Upon fertilization,the fusion of these two haploid gametes results in a diploid $(2n)$ zygote,which contains $46$ chromosomes.
